SPRING-HEEL BLANK.

SPECIFICATION forming part of Letters Patent No. 354,227, dated Decelrnber 14, 1886.

(No model.)

To all whom it may concern:

Be it known that l, FREEBORN F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of theUuited States, have invented a new and useful lmprovement in Spring Heel Blanks, of which the following is a full, clear,and exact description, reference being had to the accompanyingdrawings, forming a part of this specification, in explaining its nature.

My invention relates to a method of making spring-heel blanks, consisting in cutting the stock of which the blanks are made into long strips, and then dividing the strips by a diagonal cut or slit, then uniting the two strips so as to bring their inclined edges substantially on a line with each other, then uniting the strips together by glue, cement, metal fastenings, or in any other,desired way, and then cutting or dieing from this prepared strip the spring-heel blank. It was described originally in my application filed January 14, 1886, for which a patent was granted April 20, 1886, No. 340,358. The product is also described in Patent No. 342,461. c

Referring to the drawings, Figure l is a plan view of the strip of stock from which the blank is made, representing in dotted lines the line upon which it is cut or separated into two parts. Fig. 2 is an end elevation of said strip. Fig. 3 represents the twon parts or scctions of the strip after they have been cut and placedone upon the other and united by metal fastenings. Fig. 4 is a vertical section through the same. Fig. 5 is a plan view of said pre` pared strip, showing the form of the separate spring-heel blanks cut or dinked therefrom. Fig. 6 is a vertical section thereof. Fig. 7 represents thc ball as shaped by suitable molds to provide a heelseat. Fig. 8 is a cross-section upon the line x x of Fig. 7. Fig. 9 is a vertical section of a spring-heel shoe.

A represents a strip of stock, preferably of leather. It is cut to a width sufiieient to provide the two lifts hereinafter prescribed and of a length to provide for the cutting of a num- This strip A is divided or separated into twounequal parts by a diagonal `cut extending from thereby forming the two strips a2 a3, each of which has the straight edge a", and the i11- clined or skived edge a5. The strip a is wider than the strip a?. The strip a is then placed upon the strip a3, substantially as shown in Figs. 3 and 4, to bring the straight edges ai* together and the inclined or skived edges a5 together, as shown in said figures, and they are secured to each other by glue, paste, cement, sewing, metallic fastenings, or in any other desirable way. The strip may then be submitted to the operation of suitable formingdies, whereby the line of concave sections corresponding to the heel -seat of the finished blanks is made; or it may be submitted to a dinking or dieing machine for dinking or cutting out the hee1-blanks therefrom 5 and in Fig. 5 l have represented the line upon which said cutting-die or dinking device will operate, the strip being represented as long enough to make four heel-blanks.

If the heel-seat has not been formed by molding in the strip, as before described, it may be formed in the heel-blank, either by Vmolding or by removing a portion of the upper surface of the heel-blank; and in Figs. 7l and 8 I have represented the spring-heel blank as molded to form the seat-cavity as. cavity is surrounded by the straight section or surface al. lt is not always necessary that the heel-blank be thus shaped, as a great deal depends upon the shape of the last upon which the shoe is made. lf a llat last is used, it will be necessary to provide the spring-heel blank with a formed heel-seat. It a last considerably rounded at theheel is used, then it will be necessary or desirable to provide the blank with the heel-seat.

The strip A may be formed of leather, or of any other suitable material, or one of the strips a3, preferably a3, may be formed of other material than leather.

In use the spring-heel blank is placed between the insole and the outsole, the upper surface of the lift a3 being uppermost or next the under surface of the insole, and it is united to the insole, preferably, by a gang or group of metal fastenings driven through the outsole into the insole.

The advantages ofthe invention arise from the facility and cheapness with which blanks can be made, and also from the facility with This IOO

Which they can be used in the manufacture of boots and shoes. Heretofore it has been the custom to build the heel upon the insole by rst placing one lift thereon and securing it, then the next lift, and then the outsole, a slow and expensive method.

It is obvious that the diagonal cut may be of such a nature as to provide two parts madel from the strip A with edges which shall be more or less inclined, according to the shape which it is desired that the complete springheel blank shall have; also, that the location of the cut in relation to the edges of the strip may be varied to vary the Width of the two ,parts ce2 cti-made therefrom.

' Of course, in practicing the invention the strips a2 a3 may be formed from separate strips or pieces-that is, it is not necessary that they be eut from one piece of stock by the diagonal slit; but they should each have skived or inclined edges and each bear such relation to each other as to Width that the inclined edges, when they are placed, shall be brought substantially in line7 as represented in Figs. 3 and 4.

Having thus fully described my invention, l claim and desire to secure by Letters Patent of the United Statesl. The method of manufacturing springheels, consisting in taking a strip of stock of 3o the required dimensions, dividing it by the diagonal cut into two parts, placing one part upon the other to bring the diagonal edges in line, uniting said superimposed parts, and cutting or dinking therefrom the complete springheel blank, all substantially as described.

2. The improvement in the art of manufacturing spring-heels, consisting in forming tWo strips having skived or diagonal edges ai", placing one upon the other to bring theskived or inclined edges substantially in line with each other, fastening the two superimposed strips together, and cutting or dinking therefrom a spring-heel blank, all substantially as described.
